Implementation of DMA of PEX8311 based on FSM

结合PCI-Express的传输特性,分析了PEX8311的DMA传输模式与时序逻辑,通过有限状态机的设计,实现PEX8311的DMA传输。与其他设计相比,利用有限状态机理论设计控制逻辑具有直观、简单、设计流程短等优点,并对状态机进行了Verilog优化设计,使状态机更加稳定。

In combination with PCI-Express transmission characteristics, this paper analyzes the PEX8311 DMA transfer mode sequential logic, with FSM design, implementing the DMA of PEX8311. Compared with other designs, using the theory of FSM designs control the logic has the advantage of intuitive, simple, short design processes, etc. It optimizes the Verilog design of the state machine, making the state machine more stable.
